A Newsletter for Friends of the Western Michigan University Department of Statistics

Letter from the Chair Another year has gone by and it was again full of very productive and exciting events.

The major event organized by the Department this past year was the Great Lakes Symposium “Advancements and Challenges in the Statistical Sciences” on April 8. Three invited speakers: Dr. Noel Cressie from The Ohio State University, Dr. George Milliken, Professor Emeritus from Kansas State University and our own Dr. Michael Stoline presented talks that attracted over 70 statisticians from area universities and industry.

The Department of Statistics also celebrated its 10th anniversary with a dinner at Marie and Michael Stoline’s residence the night before.

In the coming year, there will be only eight faculty members. Dr. Michael Stoline retired on May 1, 2011 after serving WMU for 44 years. We will miss him in the classroom, but he has promised to stay in touch, attend our colloquium and simply be around for us. At the same time we are happy for Mike and his wife Marie, that they will have more time for the traveling, which they both enjoy so much.

We worked very hard last year to further improve the curricula of our programs: Mr. Loren Heun developed a new course in introductory statistics for sociology majors. He also created an on-line version of the Stat 2160 – a business statistics course. This is our second on-line course in statistics.

Drs. Paul and Terpstra designed four new graduate electives: courses in applied Bayesian analysis, spatial analysis, large sample theory, and research tools in statistical research. Already approved these new courses have modernized our graduate programs.

We are very happy to offer our newest program, an Interdisciplinary Graduate Certificate in Applied Statistics.

This certificate has been designed for non-statistics majors mainly to help students with quantitative research for their doctoral dissertations and masters theses. Students who complete these requirements will have `Certificate in Statistics’ printed on their diplomas and transcripts. This certificate program is also available to students who are not in a current program but desire a certificate in statistics for advancement in their employment.

And last but not least, we created an Accelerated M.S. Program in statistics approved this past year and available in the Fall 2011 semester. It allows talented students to obtain their Masters degree in five years from entering college. Details are available on our website www.stat.wmich.edu.

Attracting talented students and supporting them during the program could not be done without our donors. We are grateful for the generous donations from alumni, friends and companies. The money is well spent on summer support, students’ travel, conference participation, and awards. Thank you for helping us make our programs successful.

I hope you will enjoy reading the news about the department, students, faculty and alumni. Please email us any updates you would like to have included in our next issue. Your classmates and former professors would enjoy reading them.

Notable faculty and student accomplishments Dr. Rajib Paul, Assistant Professor in the Department of Statistics at WMU was married in India and a reception in Kalamazoo was held at the Holiday Inn West on June 25th. We wish Rajib and his wife Subhanwita a happy long life together.

Dr. Paul is involved in a collaborative project, titled Bayesian Hierarchical Models for Biogeochemical Cycles, with the scientists from Commonwealth of Scientific and Industrial Research Organisation (SCIRO). CSIRO is Australia’s national science agency and one of the largest and most diverse research agencies in the world.

In summer of 2009, Dr. Paul was in Perth, Australia for three months to work on this project. In this project space-time advection-diffusion models are being developed for organisms (e.g. zooplankton, phytoplankton) drifting in the water column of oceans, seas, nad bodies of fresh water. These models have some highly nonlinear features, and Gaussian error structures are at best unrealistic. Transformation offers a way forward in this latter case, but given the fundamental nonlinearity of the models, methods based on the Kalman filter, for example, are unreasonable. The main challenge in this project is to develop methodologies to deal with complex space-time models, nonstationary in space as well as nonstationary in time. There is a possibility the Dr. Paul will again visit CSIRO for a few months in Summer 2012 to continue working on this project.

3Dr. Michael Stoline Retires On July 23, 2010 the WMU Board of Trustees approved the resignation of Michael Stoline. Dr. Stoline retired officially on May 3, 2011 after 44 years of service.

Dr. Stoline’s career was celebrated with a dinner at his home for faculty and guests on April 7th, as well as a public reception at the Oaklands for the campus community, family and friends on April 29th. Among the speakers at the open house was Robert McNutt, a Ph.D. student in the department, who gave an interesting speech about admiration and imitation being the highest form of flattery.

During his commentary he mentioned the creation of “Air Stolines” high top boots which Mike generally wears

with a Nike swoosh added, and the need to wear brightly colored shirts, ties and a sports jacket.

During Dr. Stoline’s parting words, he removed his tie and said he was no longer in need of them, and his wife Marie, brought several of Mike’s ties that were given to our students as mementos and reminder of the professor they all admired and will miss. Many of the students requested that Dr. Stoline autograph the ties, and on July 1st the Stolines invited the students to a “tie signing” party at their home.

and theoretical topics in these areas as well as numerous technical reports. To share his work he has given over 60 talks, presentations and short courses at professional conferences, at universities and for various government and business organizations.

Mike took a lead role, along with statisticians at the Upjohn Company, in developing our Biostatistics Master’s program. This was a unique program in that it required an extensive internship component with a pharmaceutical company. He was the program director from 1976-89.

At Western, Mike developed connections and friendships with faculty members in other departments by helping them with data aspects of their research. This work resulted in numerous publications and generated ideas for further research. For example, in partnering with faculty in the Department of Geosciences, he became interested in environmental statistics and the issues in groundwater monitoring. He became an adviser for Michigan Environmental Regulations and wrote six reports analyzing groundwater data in counties in west Michigan. In the 1980s he was appointed to a national panel formed by

the EPA to study and make recommendations on the Love Canal Environmental Monitoring Study. He wrote numerous reports and gave over a dozen talks on various aspects of the Love Canal issues and data.

Mike was a statistical consultant for Michigan State University/Kalamazoo Center for Medical Studies in the years 1991-2000. Since the 1990s he helped organize and direct six Great Lakes Symposia. Five doctoral students completed their dissertation in statistics under his direction.

In retirement, Mike will stay active in statistics. He plans to finish his book on the design of experiments, based on many years of teaching this material to students at Western.

Along with his wife Marie, he will make many visits to the East coast to visit grandchildren. They have always traveled around the world and now they will have time to plan more of this. On a daily basis they will care for their horses and llamas and keep up with all the work on their home in the country.
